Trouble with Gender finally arrives in the US! “Arguably the most elegant polemic ever written on the subject” (The Australian).

Alex Byrne’s “colleagues” dogpile him for co-writing a critique of American pediatric gender medicine – Jerry Coyne presents a full accounting of this latest episode in cancel culture. whyevolutionistrue.com/2025/07/07/ale…
High praise from one of our best journalists: "both the opinion piece and the HHS review are superficially well argued" assignedmedia.org/breaking-news/…
One point that @johnmaier_ and I stressed in our essay was that the philosophical community ignores reasonable frustration over its mixture of errors and silence on topics like trans at its own peril. “The kind of complacent adherence to progressivism in evidence in the Yale… 1/
"Trans activists’ central philosophical arguments were always underpowered by ordinary methodological standards ... their popularization was aided and abetted by special pleading, political bullying and plain old cowardice." philosophersmag.com/philosophical-…
Notable: "We believe that this reply is the first peer-reviewed academic paper to state explicitly that Caster Semenya, and similarly placed athletes, are male, not female ..."
Here is my latest paper, published today in the Journal of the Philosophy of Sport and co-authored with Dr Emma Hilton @fondofbeetles from Manchester University. I would like to thank @OpenUniversity for their ongoing support of my research tandfonline.com/doi/full/10.10…
People often ask, "What should I look for if I want to start getting into philosophy?" A couple years ago, I didn't think there was just one resource. Now I do, and it's edited by @byrne_a & other top philosophers. I explain here: youtu.be/yk9icJaiRVw
Brilliant discussion between @byrne_a, @benappel and @JamieWhistle on the Informed Dissent podcast 👇 open.spotify.com/episode/4TpjZr…
i spoke with louise about my latest book ~feminism beyond left and right~. the first hour or so is free on youtube, the rest is at her substack (subscriber only). link below!
Happy to correct my mistakes. alexbyrne.org/mistakesupdate…
It's a stupid phrase, and it pisses me off. "Am I serious?" Of course I am. That's why I wrote the words. I think it's bad for Byrne's colleagues to form a mob. If they want to publish OpEds in the school paper criticizing his actions, better. And what false things has he said?

"I’m really glad to have engaged in ongoing discussion with someone whose philosophical perspective is very different from my own, and some of whose views I find offensive." dailynous.com/2025/07/08/the…
Excellent short doc on pediatric gender medicine (on YouTube) by @writingblock.
NEW DOC SHORT out. The fight over puberty blockers, hormones, etc. is often framed as inseparable from politics, but we show here why a broad coalition--yes, including lefties--is raising concerns or even supporting restrictions. jenniferblockauthor.substack.com/p/the-most-hea… YouTube link below.
a new video by one of the young philosophers who gives me SO MUCH HOPE for the future of our discipline & whose work i really rate. also he has really good eyebrows, it is worth watching the video for them alone. the video is about how members of minority groups don't owe...
Good timing. Moti Gorin and I have a chapter on how bioethicists and philosophers failed to properly debate youth gender medicine.
Thanks to all those who have pre-ordered The War on Science, (now #1 new release, Science Essays). (pub date 7/29) The discussions in the book illustrate forcefully the need to continue to speak out about free speech and open inquiry in academia. alturl.com/acg5e

Philosophers in a Supreme Court filing, supporting "gender medicine": "We're relevant because... we're trained in logic & arguments!!" Philosophers signing a petition against Byrne's critical review of gender medicine: "You can't do this! You... lack the requisite expertise!!"🙄
It's all Greek to me: I am on the cover of the monthly magazine the books' journal.

These scholars just met in Toronto for three days to discuss the science and other issues related to autogynephilia. Articles will be written, eventually.
